CAB, TRUCK.

Application filed April 1, 192-3, Serial N0. 39,063.

This invention lOld"S to trucks tor railway cars and, more particularly, to the construction of the side frames and associated spring plank, bolster and spring plates, whereby an additional spring unit may be employed therewith for increasing the capacity of said trucks.

The principal object of my invention, generally considered, is the improvement in design of the side frames, bolster, spring plank and spring plates, whereby a greater number of springs than normally employed may be used without radically changing the construction of the associated parts.

An object of my invention is the employment of an A. A. standard five group nest of springs together with an additional sprint group or unit spaced inwardly of the center spring of the standard nest of springs, whereby increased capacity of the truck is secured. the side frames. bolster, spring plank and spring plates being modified to a minimum extent "for efiiciently accon'iplishing the desired result.

Another object of my invention is the design of side frames, bolster, spring plank and associated spring plates for permitting the en'iployment of an additional spring unit with each side frame associated with an A. A. standard five unit nest of springs, wherebv increased truck capacity is secured, the spring plank seat portions of the side "frames being so constructed andreiniiorced by webs or brackets, ribs and stools or colun'ins, whereby an adequate area sufficiently reinforced is provided for supporting the spring plank and its associated springs, spring plates and bolster.

A, further object or"- my invention is the utilization of an additional spring unit of c(r-respondin; size with an A. R. A. standard. five unit nest of springs positioned on spring plates and an associated spring plank, bolster and side frames so that: the entire group of springs balances about the longitudinal centcrline o1 the side frame, the standard in t of springs, for that purpose, being positioned outwardly and the associated spring plank being correspondingly lengthened but formed of standard construction at its ends, the bolster being of standard construction except having the portion thereof engaging the supporting. spring assembly locally extended to receive'the addi- 'tional spring unit which is inwardly positioned. with respect to the center spring unit of the standard nest of springs.

A still further object or" my invention is the provision of an additional spring unit associated with an A. R. A. standard five group nest of springs for increasing the capacity of car trucks with which employed. said additional spring unit being positioned inwardly of the center spring unit of the standard nest of springs and on substantially the transverse center line thereof, the as-ociated spring plates being correspondingly extended to receive the extra spring uu it and provided with locating bosses arranged on the longitudinal center line of grav. y for the complete six unit nest of springs, whereby said bosses are adapted for reception in positioning apertures of standard location in the associated spring plank, said spring plank being of standard constrnction at the ends thereof but correspondingly lengthened because of the necessary shifting of the standard group of springs so that the center of gravity of the com lete group will correspond with the longituc inal center line or the associated side frame, said spring plank and side frame being formed with apertures for receiving the spring retaining; bolt, said apertures being elongated ransversely of the frame whereby they are adapted toruse with either the six unit nest of springs arranged in accordance with my invention or the A. R. A. standard nest of springs.

An additional object the modification of the side frames, bolster and spring plank of a truck, whereby the same are adapted for use with either the A. R. A. standard five group nest of springs and associated spring plates or with such a nest oi springs and an additional inwardly spaced spring group with associated spring plates.

Other objects and advantages of the in vention relating to the particular arrangement and-construction of the various parts will become apparent as the description proceeds.

Referring to the drawings illustrating my invention, the scope whereof is defined by the appended claims:

Figure l is atraginentary side elevation of a truck, shown partly in section on the of my invention is the spring plank and side frame.

line 1-1 of Figure 3 and particularly showing the construction of the various members associated with the springs positioned between the tension member of the side frame and the truck bolster.

Figure 2 is a horizontal sectional view of a fragmentary portion of the truck on the line 2-2 of Figure 1 looking in the direction of the arrows.

Figure 3 is a transverse sectional view on the lines 3 3 of Figures 1 and 4 looking in the direction of the arrows.

Figure 4 is a plan of the spring plank seat portion of the truck side frame, the position of the springs thereover being indicated diagrammatically by dot and dash lines.

Figure 5 is a top plan of the bottom spring plate and is likewise a bottom plan of the top spring plate.

' Referring to the drawings in-detail, like parts being designated by like reference characters. a truck side frame 1 is shown fragmentarily and said frame, in the presen't embodiment, is of integral cast construction embodying a compression member 2, a tension member 3, and bolster guide columns or struts 4 spacing intermediate portions of said compression and tension members, leaving a bolster or window opening 5 therebetween. The compression member 2, over the bolster opening. is shown substantially channel or inverted U shape in cross section, the bolster guide columns are shown of similar construction at the bolster guiding portions thereof whereas the tension member 3, beneath the bolster opening 5, is illustrated as of box shape in cross section and formed with an upper web 6, a lower web 7 a front or outer web 8 and a rear or inner web 9, said webs 8 and 9 being upright or substantially vertical and extending between the webs 6 and 7. As will be apparent from a consideration of Figure 3, the webs 8 and 9 join the web 7 at the side edges thereof but the upper web 6, in order to form a spring plank seat portion of ample width, is extended laterally beyond the upper ends of the webs 8 and 9 forming outward or front flange or shelf portions 10 and inward or rear shelf or flange portions 11.

In the embodiment illustrated, the spring plank 12 rests directly on the upper web 6 of the tension member which forms the seating portion therefor and the upper surface of said spring plank seat portion is preferably formed with A. R. A. standard squaring lugs 13 which engage in corresponding apertures 14 in the spring plank for maintaining the desired relation between The end of the spring plank 12 is of standard construction and provided with a regular A. R. A. embossment 15 to prevent the associated spring group from working out. In accordance with my invention, however, the length of the spring plank is slightly greater than the standard spring plank because of the additional spring group or unit which may be used therewith although it is adapted for use with the A. R. A. standard five group nest of springs, if desired. The spring plank 12, as shown most clearly in Figures 1 and 2, is of channel construction and the web thereof is formed with spring plate locating apertures 16 so positioned that when the spring plank is assembled with the side future, said apertures 16 are located on the longitudinal center line thereof.

Positioned on the web of the spring plank 12 is a spring plate 17 formed with locating bosses 18 which engage in the apertures 16 in the spring plank and properly position the spring plate 17 and the associated springs 19. In the embodiment illustrated, the bosses 18 are formed by pressing substantially conical extensions downwardly from the spring plate 17 but it is obvious that they may be of any desired construction. In accordance with my invention, I preferably employ an A. R. A. standard five group nest of springs which is positioned directly on the spring plate 17 and properly located with respect thereto by means of upstanding annular flanges or collars 20 which engage the inne most springs 21 of the spring groups or units 19.

Positioned inwardly of the center spring unit 19 of the standard nest of springs, in the present einbodin'lent, is an additional spring unit or group of springs 22 preferably corresponding in size with the other spring groups or units of the standard nest of springs. In order to accommodate this extra spring unit or group, the spring plate 17 is correspondingly extended, as shown most clearly in Figure 5. and formed with an additional spring locating collar 23. The additional group of springs 22 is preferably spaced with respect to the springsof the standard group in accordance with the spacing between the springs of said group, pref erably lies on the transverse center line of the central group of springs and inwardly disposed with respect thereto. The locating bosses 18 are so arranged with respect to the collars 20 and 2?) that the springs balance about said bosses.- that said bosses preferably lie on the longitudinal center line of gravity of said springs so that. when engaged in the locating apertures 16 in the spring plank 12, the s 'iriugs balance about the longitudinal center line of the frame, either when said'springs are in accordance with my invention, as shown in the drawings. or if they are replaced by a standard live group nest of springs in which the loeating bosses are also on the longitudinal center line of gravity of said springs.

The upper spring plate 24 may be constructed identical with the lower sprgig plate 17 but is reversed in position so that the collars 20 and extend downwardly and engage the inner springs 21 and the locating bosses 18 extend upwardly and engagein corresponding apertures, not shown, in the truck bolster 25. Referring particularly to Figure 3, it will be seen that because of the sixth spring group or unit 22, it is necessary to extend the substantially horizontal spring engaging web or face 26 of the bolster inward as shown at 2'7. This, however, is only done locally so as not to decrease the bolster strength at this point any more than is necessary, the outer sides of the sloping portion 28 of the lower web of the bolster starting to slope at its standard location, as indicated at 29, and the horizontally extended portion 27 of the web 26 being thickened, as indicated, to avoid decreasing the bolster strength.

F or retaining the spring plates 17 and 2-1- in the desired assembled relation with respect to the springs therebetween, the spring locating collars engaging the central spring set or group of the standard nest of springs are preferably formed substantially semispherical in shape and, as indicated most clearly in Figure 3, provided with apertures 30 therethrough for the reception of a retaining, bolt or other means 31 extending therebetween.

Inorder to allow for compression of the springs due to the load of the car, the spring plank 12 is apertured at 32 directly beneath the bolt 31 and the upper web 6 of the ten v sion member of the side frame is correspondingly apertured at 33. In order that the apertures 32 and 33 may be adapted for use either with the spring arrangementshown in accordance with my invention or with the standard five unit nest of. springs heretofore referred to, they are preferably elongated transversely as shown most clearly in Fig ures 3 and 4 so as to overlap the center line of the side frame 1 and alloi' for the reception of a bolt 31 positioned as shown in Fi ure 3 or tor one positioned on the center line of the side frame in accordance with standard construction.

For adequately reinforcing the spring plank seat or upper 'web 6 of the tension member 3 of the side frame with respect to the novel arrangement of springs in accordance with my invention, said web 6 is preferably formed and reinforced as most clearly shown in Figures 3 and i. From a consideration of these figures. it will be apparent that the front edge of the web 6 is extended in width to a maxnnun'i below the two outer spring'groups or units 19 and between these points extends in a straight line at a uniformdistance from the center line of the frame. as indicated at 3%. Approximately directly beneath said outer springs, the extended flange 10 is preferably reinforced and braced with respect to the web 8 by means of substantially triangular web or bracket portions 35. The inner edge of the web 6 or the free ed 'e of the flange portion 11 thereof is incrc: ed in width to a in: ximuin dir ctly beneath the innermost or extra spring unit 22 as indicated at 36 and is there preferably reinforced by a substantially triangular web or bracket 37 extending from the webi) of the tension member.

is a further reinforcement for the spring plank seat portion or web (5 of the tension member, a plurality of columns or stools 38 preferably angular or star shaped in cross section are provided between webs 6 and 7 of the tension member, said stools 38 serving principally for supporting the spring units above, and which, as shown most clearly in Figure 1, are those springs which lie directly inward of the two outermost spring inits. Further spring plank seat reinforcing means, in accordance with the present eml'iodin'ient, comprise the upright webs or ribs 39 a d att) which extend preferably in line with the web 37 and aperture 33 in the web 6 and lie benea h the center spring unit of the standard group of springs and the extra spring unit inwardly positioned theretron'i and, therefore, serve principally for supporting these spring units. It will be apparent that, although the aforedescribed reinforcement is especially designed for the six unit group of springs in accordance with my invention, yet it is adn'iirably adapted for supporting the A. R. A. standard five grroup nest of springs when the same is positioned. so that its longitudinal center line of gravity coincides with the longitudinal center line of the side frame.

From the aforegoing dhclosure, it will be seen. that I have devised a construction which provides for a twenty per cent in crease in spring capacity without radically changing the construction of the side frame, spring plank and associated bolster. Vi ith said modified members, the A. R. A. stand ard live group nest of springs may be em-v ployed interchamreably with the spring arrangement disclosed in accordance with my invention although, of course, there will be slightly more clearance between the sprin plank embossment 15 and the standard live group nest of springs normally positioned than when employing the spring arrangement disclosed in the present application.
